Abstract: 1,214,328. Television signal recording; multiplex signalling; radio receiving circuits. IIT RESEARCH INSTITUTE. 3 Nov., 1967, No. 50173/67. Headings H3Q, H4F and H4L. In a magnetic recording system in which a recorded record medium is produced, the intermediate frequency audio carrier is separated from the video signals by means of a resonant circuit 15 and heterodyned 28 with a reference carrier signal to produce a lower frequency carrier which lies within the effective pass band of the magnetic recording system. This lower frequency audio modulated carrier is combined with the video signals and recorded on a single track of the magnetic tape. The recording audio carrier frequency is preferably an odd multiple of half line scanning frequency. The video signal may comprise a colour television signal, the frequency of the reference carrier signal being the chrominance subcarrier frequency. Upon playback the audio carrier is heterodyned with the reference carrier to produce the original I.F. audio carrier which may be applied directed to a television receiver together with the video signals. Reference has been directed by the Comptroller to Specification 1,148,231.

Abstract: 1443974 Lasers MASSACHUSETTS INSTITUTE OF TECHNOLOGY 30 Oct 1973 [30 Oct 1972 26 Feb 1973] 50445/73 Heading H1C A gas laser is pumped by the combination of a light source which photoionizes at least a constituent of the gas and an electric discharge, photoionization occurring predominantly by a multiple step process involving absorption of successive photons any one of which has a photon energy less than the ionization potential of the responsive gas constituent. As described the gas may be a CO 2 -N 2 -He mixture with an added photoionizable constituent consisting of tri-n-propyl amine, tri-butyl amine or tripentyl amine; the gas flowing between inlet and outlet 140, 142 of a gas laser tube 110, Figs. 4 and 5. The tube is terminated by plates 112, 114 respectively supporting a highly reflective gold plated curved mirror 116 and a partially transmissive curved germanium window 118. Within the tube chrome plated parallel aluminium electrodes 122, 124 are supported by phenolic rings 126, 128 and quartz-walled xenon flash lamps 132, 134 are mounted for optical pumping. The electrodes and lamps are respectively energized from power supplies 131 and 138 by way of an energy storage capacitor 130 and a capacitor-triggered spark gap 136. If the electrode potential is insufficient to cause an avalanche discharge it is applied at the same time as the optical pumping. Otherwise it is interrupted by a switch 125 which is closed by a timing circuit 123 after optical pumping commences. An alternative form of optical pumping is shown in Fig. 6 in which flash lamps 154, 156 outside the gas tube apply light beams directed by reflectors 150, 152 through a dichroic resonator reflector 116<SP>1</SP>. Within the tube the beams are repeatedly reflected in zig-zag fashion along the tube length by mirrors 158, 160. This pumping arrangement may be wholly within the tube, the diochroic reflector being then omitted. In an alternative construction, Fig. 7 (not shown), photoexcitation and electric field excitation occur in separate coupled chambers. It is stated that with suitable primary laser gas constituents the need for an added gas component does not arise.

Abstract: 1,157,909. Filling containers. BRATBY & HINCHLIFFE Ltd. 7 Nov., 1967 [19 Nov., 1966], No. 51908/66. Heading B8T. In a method of filling a container 20 the air in it is flushed out by pressurized gas prior to sealing of the container against a filling head 11, after which the container is counterpressurized before being filled. An annular filling tank 10 and container supports 21 are arranged to rotate around a vertical axis. A gas valve 17 operated by a fixed cam rod 19 and a counter-pressure cam 18 permits gas to enter into a counter-pressure tube 13 and out of a distributer 14. Each filling head terminates in a cup 12 into which is fitted an annular sealing member (12a), Fig. 3 (not shown) against which a container abuts during filling. Vertical movement of the upwardly biased container supports is controlled by followers 22 and a container-support cam track 23. The track has a level portion 28 giving a dwell in the raising movement of the container-support just before the container seals against the member (12a) with the cam rod 19 positioned so that gas is supplied through the tube 13 during this dwell. When the follower runs off the level portion, the container is raised and seals with the filling head. The container is then counter - pressured in a known manner so that a pressure valve (not shown) opens upon pressure build-up in the container to permit a flow of liquid into the container. The container-supports need not be biased upward. Their movement is controlled by a cam track 23a with a pneumatic ram to give the final movement needed to seal the container with the filling head. The ram is operated after the level portions 28a by a member 34 co-operating with a compressed air valve 35. Appropriate switching off of the valve 35 is effected by similar means and the supports are lowered by gravity.
